Stock wheel color

So I woke up early to do outside work since it is a wonderful 70 degree morning here in central florida.

I took some oven cleaner to the rims front and did a scratch test after that...pure black down to the.metal.

So I get under the car and take oven cleaner to the backs...all of the rims back had a now greenish (probly years ago turquoise) back.as my member photo shoes the car is white and build numbers/Vin show it as a white car with turquoise interior.

My only guess is that sometime early in its life the rims were sprayed to match the interior, then in the 1980's when it was partially re sprayed they stripped the front and shot them black.
